DESCRIPTION

16       The command creates in the current directory an HTML web page  contain‐
17       ing  multi-exposure  HDR  viewer.  The multi-exposure viewer displays a
18       portion of the available dynamic range with  minimum  contrast  distor‐
19       tions  and  provides  a slider control to move the dynamic range window
20       towards brighter or darker tones. The  interface  is  very  similar  to
21       pfsview, which is a pfstools application for displaying HDR images. The
22       web page employs only JavaScript and CSS opacity property and does  not
23       require  Java applets or the Flash plugin. Note that because this tech‐
24       niques encodes 20-60 exposures using only  few  images,  the  displayed
25       exposures  may  not  be  identical  to  the exposures that are shown in
26       pfsview. For examples and more information, visit
27
28       http://pfstools.sourceforge.net/hdrhtml/.
29
30       <page_name> specifies the file name, of the web page to  be  generated.
31       If  <page_name> is missing, the file name of the first image with .html
32       extension will be used.
33
34       The command can take as input several images and put them  all  on  the
35       same web page. For each image, its file name (from the FILE_NAME tag in
36       the pfsstrem) without extension and a leading path will be  used  as  a
37       name  for  all JavaScript variables corresponding to that image. If the
38       filename contains illegal characters (such as space,  '-',  '[',  etc),
39       these will be converted to '_'.
40
41       --quality <1-5>, -q <1-5>
42              Quality of the interpolated exposures, from the worst (1) to the
43              best (5). The default is 2, which is sufficient for most  appli‐
44              cations.  Higher  quality will introduce less distortions in the
45              brightest and the darkest tones, but  will  also  generate  more
46              images.  More images means that there is more data that needs to
47              be transferred  to  the  web-browser,  making  HDR  viewer  less
48              responsive.
49
50       --image-dir <directory_name>, -d <directory_name>
51              Specify  where  to  store  the  resulting  image files. Links to
52              images in HTML will be updated accordingly. This must be a rela‐
53              tive path and the directory must exist.  Useful to avoid clutter
54              in the current directory.
55
56       --page-template <template_file>, -p <directory_name>,  --image-template
57       <template_file>, -i <template_file>
58              Replaces  the  template files used to generate an HTML web page.
59              The template files contain all HTML  and  JaveScript  code  with
60              special  keywords  (@keyword@) that are replaced with image spe‐
61              cific data, such as width, height, image  base  name,  etc.  The
62              default  template  files  can be found in INSTALL_DIR/share/pfs‐
63              tools/hdrhtml_*_templ.html. See TEMPLATE FILE FORMAT below  more
64              details.
65
66       --object-output <file_name.js>, -o <file_name.js>
67              Store  JavaScript objects (hdr_<base_name>) associated with each
68              image in a separate file. This is useful if you want  to  script
69              creating HTML pages.
70
71       --html-output <file_name.html>, -l <file_name.html>
72              Store  HTML  code  that shows HDRHTML viewer for each image in a
73              separate file. This is useful if you  want  to  script  creating
74              HTML pages.
75

TEMPLATE FILE FORMAT

77       pfsouthdrhtml  uses  two  template  files  hdrhtml_page_templ.html  and
78       hdrhtml_image_templ.html, located  in  INSTALL_DIR/share/pfstools/,  to
79       generate  a  web page with an HDR HTML viewer. The 'page' file contains
80       the HTML of the entire web page and the 'image' file is used to paste a
81       viewer  code for a single image. You can replace one or both these tem‐
82       plates  with  your  own  using  --page-template  and   --image-template
83       options.
84
85       Each template contains HTML code with additional keywords surrounded by
86       @ marks (@keyword@), which are replaced with HDR  HTML  specific  code.
87       Most  of  the  keywords  are  self explanatory, therefore only the most
88       important are described below.
89
90       @hdr_img_def@ JavaScript objects that must be put in the 'body'
91              section before any  images.  These  define  all  the  parameters
92              needed to control HDR HTML viewer.
93
94       @cf_array_def@
95              Pre-computed  array  of  opacity coefficients. The same array is
96              used for all images that use the same quality setting. Currently
97              only one such array could be used per web-page, so images gener‐
98              ated with different quality setting cannot be mixed on a  single
99              web page.
100
101       @image_htmlcode@ or @image_htmlcode[base_name]@
102              Inserts  HTML  code  of  all  images  or a single image with the
103              base_name (name with no file extension) specified as  a  parame‐
104              ter. This should be put where HDR HTML viewer should be located.

EXAMPLES

107       pfsin memorial.hdr | pfshdrhtml memorial_church
108              Generates  a  web page memorial_church.html with a set of images
109              memorial_church_*.jpg in the current directory.
110
111       pfsin ~/hdr_images/*.exr | pfssize --maxx 512  --maxy  512  |  pfsouth‐
112       drhtml hdr_images
113              Generate  a web page with all OpenEXR images from ~/hdr_images/.
114              The images are resized so that they are not larger than 512x512.
